This paper focuses on lexical ambiguity. With respect to mathematics classrooms, polysemy has been mentioned as one of the principal concerns, namely certain words having different but related meanings. It may also happen when different meanings of a word are presumed in everyday context and in another environment, in this case in mathematics register. Focus is placed on the two examples of polysemous terms, divisor and quotient. Classroom vignettes are provided to discuss the use of those terms in the mathematics classroom and outline the confusion about the meanings of those terms. (ASK)
